SPINNING-SPINDLE.

SPECIFICATION forming part of Letters Patent No. 386,810, dated July 31, 1888.

Application filed April 26, 1888.

To all whom it may concern:

Be it known that we, RICHARD GILL, of Methuen, in the county of Essex, and WILLIAM H. BUTLER and SAMUEL SMITH, both of Lawrence, in the county of Essex, State of Massachusetts, have invented a certain new and useful Improvement in Spindles, of which the following is a description sufficiently full,clear, and exact to enable any person skilled in the art or science to which said invention appertalns to make and use the same, reference bcing had to the accompanying drawings, forming part of this specification, in which- Figure 1 is a vertical longitudinal section of our improved spindle, including portions of` the rails, certain parts being shown in side elevation; Fig. 2, a horizontal section taken on llne x .fr in Fig. l; Fig. 3, a side elevation Vof the bushing detached, a portion of the oilcup being represented as broken away to show the spirally-grooved body; and Fig. 4, a side elevation of one ofthe fliers, the flier-ring, and a portion of the guard.

Like letters and figures of reference indicate corresponding parts in the different figures of the drawings.

Our invention relates to that class of spindles which are provided with iiiers and designed principally for worsted-spinning; and it consists in certain novel features, as hereinafter fully set forth and claimed, the object being to produce a more effective and otherwise desirable device of this character than is now in ordinary use.

The nature and operation of the improvement will be readily understood by all conversant with such matters from the following explanation.

In the drawings, A represents the spindle proper, B the movable or lifting rail, and C the stationary or step rail.

The spindle A is threaded at its lower end and screwed into the lifting-rail B, where it is secured in any desired position by the check-nuts D.

A vertically-arranged bushing, E, is inserted in the rail C, said bushing being centrally provided. with an annular oil-cup, F, which rests on the upper side of said rail and has a narrow inwardly projecting annular flange, a, at its top.

Serial No.271.93l. (No model.)

The body b of the bushing is extended upwardly above the cup F, and exteriorly provided with two spirally-arranged grooves, 44, running in opposite directions, one to the left and the other to the right, said grooves crossing and recrossing each other7 as shown in Fig. 3.

A vertically-arranged sleeve, G, is fitted to revolve on the body b of the bushing E, the lower end of said sleeve having its bearing on the bottom of the oil-cup F. This sleeve is provided at its upper end with a large horizontally-arranged disk, el, having a peripherally-disposed upwardly-projecting iiange, f, and near its lower end with a whirl or pulley, g, from the lower side of which a verticallyarrangcd annular iiange, h, projects in the oilcup F, thereby forming the annular oil-chamber 'L'.

' A cylindrical metallic guard, H, provided with a ring, J, at its upper end, is secured to the disk d within the fiangef, said guard serving to a great extent to overcome the resistance of the atmosphere to the revolutions of the bobbin, and thereby prevent it from interfering with the proper laying of the fibers of the yarn as the bobbin is revolved. It also enables the spinner or operator of the frame to readily stop the revolutions of the fliers, when desired, by grasping said guard with the hand.

A vertically-arranged flier-arm,l, provided with a slotted eyelet, k, through which the yarn passes from the rolls, and also withaslotted eyelet, m, for guiding the yarn to the bobbin, is inserted in a hole in the ring J, and has its lower end firmly secured to the disk d, a counterbalancing dier-arm, L, being secured in like manner at the opposite side of said ring and disk, as shown`in Fig. l.

Fitted to slide vertically in the bushing E, around the spindle proper, A, there isa tube, M, which extends upwardly above the disk d, and is provided at its top with a cup-shaped rest, 24, in which afriction-ring, 25, composed of felt, leather, or any other suitable material, is placed, said ring being inclined outwardly on its inner side, as shown in Fig. l. The

upper portion of the spindle A is turned down or reduced, as shown at 26, and the upper end of this portion still further reduced to form the shoulder 27', on which is disposed a raw: hide ring or bearing, 28.

A bobbin-tube, N, provided with a cap, 2-9, having a vertical hole at its center, is mounted on the upper portion ofthe spindle A, the reduced upper end of the spindle above the ring 28 being inserted in the holein said cap, which cap rests on said ring and thereby suspends the tube. The tube N is provided at its lower end with a boss, 30, having its sides inclined inwardly to correspond approximately with the outward incline or angle ofthe inner side of the friction-ring 25, said boss being provided on its upper side with studs or projections 32, adapted to enter corresponding recesses in the lower end of the bobbin. (Not shown.)

.An annular groove, 33, is cut in the body of the spindle proper near the bottom of its reduced portion 26, and secured in the lower side ofthe boss 30 there is a bent pin, 3i, the free end of which is inserted in said groove, said pin preventing the tube Nfrom being accidentally withdrawn from the spindlein doffing. As an additional precaution to prevent the bobbin-tube from being accidentally withdrawn, as described, a nut, 35, is placed on the upper end of the spindle, said nut being turned down into close proximity to the cap 29, but not sufficiently to bear" thereon. The nut may, however, be omitted when the pin 34 is used, and vice versa, if desired.

A tension-nut, O, is placed on the lower portion of t-he body of the spindle A, between the lower end of the tube M and uppermost checknut, D, said tension-nut being adapted to raise said tube and force the friction-ring 25 in the rest 24 against the boss 30 on thelower end of the bobbin-tube N, thereby enabling any desired degree of tension to be readily placed on the bobbin. The ringJserves to brace the fliers K L, and when the cylindrical guard H is not used said ring is attached directly to the fliers. The ange h on the whirl g does not extend quite to the bottom of the oil-cup F, thereby permitting the oil in said cup to pass into the chamber ,where it will be held and delivered gradually as the whirl revolves, thus largely preventing the oil from being thrown from the cup by the revolutions of the sleeve G, a suffiicent quantity of oil being taken up by capillary and centrifugal action to lubricate the bearing-surfaces of said sleeve.

It will be understood that the spindle A is raised and lowered vertically with the rail B, producing corresponding reciprocating movements of the bobbin on the tube N, and that the sleeve G and flier-arms K L are revolved in horizontal planes around the spindle, but do not move vertically. The grooves 44 serve to retard the oil as it passes upward from the cup F between the sleeve and bushing,thereby preventing it from being carried abovethe bushing and wasted.

If preferred, the upper end of the spindle above the portion 26 may be inserted in a socket in the cap 29 without being reduced. The dier-arm L being employed for counterbalancing the dier-arm K, any other suitable means for that purpose may bel used, if desired. Thegreen-hide bearing 28 may also be` omitted, if preferred, or a bearing of some other suitable material substituted therefor.
